∠a and \angle b∠b are complementary angles. if m\angle a=(8x-28)^{\circ}∠a=(8x−28) and measure of angle b=(8x+22) ∠b=(8x+22) ,then find the measure of angle b∠b.

Step-by-step explanation:

Basically we want to find x and then plug that in for angle B.  How do we find x?  Well, we know the angles are complimentary, which means theya dd to 90, so let's start with that.

A + B = 90

8x - 28 + 8x + 22 = 90

16x -6 = 90

16x = 96

x = 6

So there we go.  Now to find B

B

8x+22

8(6)+22

48 + 22

70

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
